Hmmmm. It's just an association of two phenomena, which could be completely unrelatedand thus, worthless as science. But hang on, I have an idea of how a causal relationship might actually exist:
First, it's been established in peer-reviewed scientific journals (but not the mainscream media) that women who have induced abortions increase their lifetime risk of breast cancer by approximately 40 percent. This background fact helps us generate an hypothesis that might explain the associattion of the phenomena mentioned above:
Part I: The cohort of women who self-identify as victims of racial discrimination includes a large proportion who are in denial about their own responsibility for what happens to them in life.
Part II: Furthermore, suppose that the cohort of women who live in denial about their own responsibility for what happens to them includes a large number who have sex outside of marriage, and then get induced abortions.
The hypothesis is testable. Think Howard's scientists will be interested?
Ergo, those who perceive racial discrimination have a separate reason for having a higher breast-cancer rateand it happens to be a factor in both. That reason would be: a habit of psychological denial.
